* fix(multi-instance): publish skill_manage cache resets and tolerate a concurrent namespace create
Two leftovers from the multi-instance work (#7097).
The agent's skill_manage tool refreshed only its own process's skills
prompt cache after a create, edit, patch, delete, write_file or
remove_file, so a Gateway replica sharing the home volume kept rendering
that user's previous skill list. Every mutation now runs one drained tail,
as the skill routes do: the write and its history record, the local
refresh, then publish_skills_cache_reset(user_id=...) off the event loop.
A run cancelled while the write is in flight still refreshes and
publishes before the cancellation propagates. A marker that cannot be
written is logged inside the tail and raised as SkillCacheResetPublishError
with a message saying the change was applied, so the model does not retry
a write that succeeded.
Two provisioner replicas starting together against a missing
K8S_NAMESPACE both read 404 and both create; the loser's 409 escaped the
lifespan and crashed it. A 409 on create now counts as the namespace
existing, as the Pod and Service creates already do.
Also drops a stale duplicate of the multi-instance "declaration also
drives" note in CONFIGURATION.md.
* docs(changelog): reference #7099 for the multi-instance leftovers

* fix(skills): keep custom-skill edit checks off the event loop
update_custom_skill built the user-scoped storage, ran the editability
probes, validated the frontmatter through a temporary directory and read
the content being replaced on the Gateway loop; only the write and history
append had been offloaded. Run the pre-scan checks in one worker and the
replaced-content read in another, matching rollback_custom_skill, and build
delete_custom_skill's storage off the loop as well.
* fix(skills): build skill storage off the loop in install and skill_manage
The same sweep that moved the custom-skill edit checks off the loop finds
two more storage lookups on it: the archive-install helper behind both
install routes, and the agent's skill_manage tool, whose lookup resolves
and stats config.yaml on every call. Offload both, and pin that the
caller's user context still reaches the storage lookup now that the edit
route resolves it inside a worker.
* docs(changelog): reference #6332 for the skill storage off-loop fix
